CAR-STAKE AND POCKET.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Application filed March 3, 1913. Serial No. 751,846.

To all whom it may concern:

Be it known that I, CORNELIUS H. VAN- DONK, a citizen of the United States, residing at lVells, in the county of Delta and State of Michigan, have invented a new and useful Improvement in Gar- Stakes and Pockets, of which the following is a specification.

This invention is an improvement upon patent granted me April 30, 1912, Number 1,024,608.

One object of the invention is to provide a device of this kind in which the pocket will not project beneath the car sill thereby adapting the same for use with certain types of cars with which it is not convenient to have the operating shaft or any part of the pocket extend beneath the car.

The invention also consists of a number of improvements in mounting the various parts, as well as minor improvements in the construction of the pocket itself, all of which will be hereafter explained in detail, pointed out inthe claims and shown in the accompanying drawings, in which:

Figure l is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a vertical section through thepocket the door being shown in open position. Fig. 4 is a longitudinal section through a bushing carrying certain operating segments. Fig. 5 is a sectional detail view illustrating the construction of a two part bushing for an operating shaft, taken on line 5 5 of Fig. 2. Fig. 6 is a detail sectional view illustrating the reinforcement of ahook. Fig. 7 is a side elevation of abusliing especially adapted for use with a modified form of pocket. Fig. 8 is a side elevation of such modified construction of pocket. Fig. 9 is a front view of said pocket, the door and operating means being removed.

The operation of this pocket is substantially the same as that of the pocket set forth in the patent referred to, and the said pocket is designed to hold a stake constructed in accordance with the one shown in my previous patent.

In the above described drawings, 1 represents the pocket and it will be noted that the rear wall2 of the pocket and the bottom 3 slope downwardly and outwardly, so that when the front door swings. downwardly into the position shown in Fig. 3 the stake will readily fall from the pocket thereby avoiding all danger of the stake becoming jammed in said pocket. The door 4- is provided with a hook member 5, and said hook member is reinforced and strengthened by a side web 6, said web serving also as a side-wall of a pocket and preventing the parts becoming accidentally unhooked by lateral displacement of the shoulder of a pivoted look ing member 7 which is engaged by the book 5 when the door is in closed position. This locking member corresponds to a pivoted arm shown in my previous patent. The shape of this part has been changed and I have also improved the manner of mounting the same upon the pocket. This improvement consists in forming upon the back plate of the pocket outwardly extending lugs 8 slightly spaced from the pocket and the locking members 7, there being one upon each side of the pocket, are pivoted between said lugs and the sides of the pocket, respectively. By means of these lugs and the reinforcement of the hook members 5, the looking member 7 is limited to movement in a vertical plane only. This, of course increases the movements of the parts in the manner designed, and also decreases the likelihood of the lockingmembers being accidentally twisted or torn from their proper positions. Below the bottom 3, the sides of the pocket are extended downwardly forming parallel brackets 9 and in said brackets I journal a sleeve 10, one end of which carries an integral segment 11 and the opposite end is squared and upon said squared portion is fitted a similar segment 12. These segments are also provided with integral arms 13, the extreme ends of which are slightly curved to cooperate with the slightly curved face of an operating point 1% carried by each locking member 7. The door is also hinged by a suitable pintle 15, which passes through said brackets and suitable downwardly extending lugs 16 and said door is provided with a suitable spring 17, which throws the same downwardly and holds it in position beneath the pocket as shown in Fig. 3, thereby making it absolutely certain that the lower end of the stake will not catch or hang upon any portion of the door but would clear the pocket and all parts attached thereto. J ournaled in the brackets 9, I also arrange a two part bushing 18, saidloushing being divided into two half sections, the inner end of each of which is partly cut-away leaving interlocking hook members 19. The sleeve 18 like the sleeve 10 has a squared bore and is adapted to re-* ceive an operating shaft 20, similar to the one shown in my previous patent. The sleeve 18 also carries segments 21, which are adapted to mesh with the segments 11 and 12. These intermeshing segments also carry at an end of the toothed sections blunt teeth or shoulders 22, which when they engage each other act as stops and limit turning movement of the intermeshing segments. This prevents the segments being turned into such position that the teeth of one seg ment will clear those of the other.

It will be obvious from the above description and the drawings that when the shaft is rotated the gears 21 will be rotated from right to left, and the gears 11 and 1 from left to right, thereby swinging the arms 13 upwardly so that they will free the tapering points 14 of the locking members 7, thereby permitting said locking V members to drop into a substantially vertical'position, thus withdrawing the shoulders 7 from the hook members 5, and permitting the spring 17 to throw the door 4 into open position.

In order to adapt the pocket above described to a certain type of car in which it is not desirable for the brackets 9 or the operating shaft 20 to extend beneath the car sill I provide a formof pocket 23 shown W in'Figs. 8 and 9 and which is provided with substantially the same parts as the pocket 4.

with the exception that the depending brackets 24-do not extenddownwardly beneath the car sill as do the brackets 9. This of course reduces the bear-ing surface of the brackets and consequently a dlvided bushing 25 similar to the sleeve or bushing 18 is mounted in suitable bearings 26 formed in the brackets 24 and these bushmgs instead of being provided with segments or mutistruction the under-hanging of the parts is lated gears carry directly arms 27 which correspond in size and shape to the arms 13, and cooperate in the same way with the tapering points 14 of the locking members 7. The bushing 25 also carries at each end suitable stops 28 adapted to engage the looking members 7 and limit relative movement of said arm and said hook members. It will be noted that in this last described conentirely avoided.

hat I claim is: 1. A stake pocket having a, forwardly inclined rear wall and a forwardly and downwardly inclined bottom, the side walls of said pocket extending downwardly below said pocket, a spring pressed door adapted to close the front of the pocket, means for operating means journaled in said side walls and below said bottom for the purpose of releasing said door.
